Urban Tree Risk Assessment – Perceptions, Reality, and Reliability

2013 | Dr. Andrew Koeser, University of Florida

This project will address three aspects of risk assessment: 1.) Factors driving homeowner and professional risk perceptions; 2.) Impact of individual arborist on common risk assessment method outcomes; and 3.) Relationship between target rating and actual site occupancy given time of assessment. These efforts represent the beginning of a larger research program to assess the reliability of commonly used risk assessment methods (ISA Tree Hazard Evaluation Method, USDA FS Community Tree Risk Evaluation Method, and ISA Tree Risk Assessment BMP Method) and improve tree risk prediction models. Results from the risk perception aspect of this project are intended to identify areas were risk perception and risk reality are misaligned – offering guidance for industry and public education efforts. The remaining aspects of this project are intended to be an independent assessment of past and emerging risk assessment methods.
